How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Kansas using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Kansas's RPP is 0.9 (national baseline = 100) and its BLS labor adjustment factor is 0.91. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(Kansas) = 0.9 · BLS adj = 0.91
